Build initrd Image

This build will create an initial RAM disk as a permanent root filesystem in NAND.

On kernel startup, the bootloader pass the load address of initrd image to the kernel to uncompress and copy the contents of the image into RAM, then frees the memory used and mount it as the initial root file system.

In addition jffs2 and cramfs is can also be used to write to the root filesystem.
